About this 1.54ct lab-grown cushion diamond

This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG846643057 or 846643057. Listed at 8 retailers as of November 4, 2026, with prices from £228 to £843, a £614 spread on the same certified stone. With Clarity lists it at £843. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
